essentially marx was so moved by stirner’s devastating attack on ‘philosophy’ that he was simultaneously intrigued and terrified. so he did what any innovative thinker would do; dismantle it before it turned the whole world into a shit-storm, and then put it back together for use against the bourgeois concepts of history that rested so firmly on the philosophical nonsense that supplanted it. so stirner was good and bad; good in demolishing the philosophical idealism/rationalism that elevated the ruling classes over the productive classes, bad in doing such a fantastic job at it, that the almost impossible task of re-centering egoism in favor of history and the proletariat - rather than descending into nihilism - would require a sustained attack on philosophy through the marxist materialists. a culmination of this movement arrives in positivism, wittgenstein, and the ‘ordinary language’ philosophers.
regarding the lacan question, yeah, sorta. what we have today are not spontaneous philosophical questions that arise from nowhere in the heads of philosophers. language is literally like a logocentric superstructure that designs and contains the anatomy of all possible questions… so that today, when doing philosophy, one is absentmindedly participating in an ideology that involves all kinds of presuppositions that are taken for granted. a great example would be nationalistic philosophies that are grounded in social darwinism. this is neither a science or a philosophy, but rather a series of hackneyed attitudes held by conservatives. i think it was lacan who said ‘ideology; they don’t know it, but they are doing it.’ what this might mean here is that such pseudo-philosophy has become so entrenched in modern thinking that in order to dispel its mythology, you’d have to demolish centuries of thought.
all this only has currency in marxist terms; that the ideas of each epoche are established by the ruling classes. ergo, capitalism mobilizes a vast series of pseudo-philosophical truisms in its attempt to rationalize and defend itself. the presuppositions of philosophies upholding this ideology were both destroyed and preserved by stirner. by reducing all institutions down to ‘spooks’, he set the ego free… but in doing so he opened the door for radical, amoral individualism… precisely the kind we see at the foundation of western capitalist theory.
